How long should you wait if you do not hear "No1 to the flight deck" or feel descent after oxygen masks drop down?

In situations where oxygen masks drop down, waiting for a specific duration before taking further action is crucial for ensuring the safety of both crew and passengers. The recommended waiting time of 1 minute is determined based on standard crew protocols, allowing sufficient time for communication and situational assessment among the flight crew.

During this minute, crew members typically check for any signals or communications from the flight deck regarding their status. If they do not hear "No1 to the flight deck" or notice a descent, it is an indicator that the situation may require further escalation or intervention. One minute is a balanced duration that acknowledges the urgency of cabin safety while also enabling the flight crew to address any immediate issues effectively.

This approach emphasizes the importance of communication and situational awareness among crew members, which are key elements in Crew Resource Management. By waiting for this predetermined time frame, the crew can make informed decisions about the next steps, ensuring that safety protocols are followed effectively in response to the drop of oxygen masks.
